Acoustic Noise Generator

Item#: ANG-2200

The
ANG-2200 is designed to create a
perimeter of noise around a target
area that defeats wired microphones
inside walls, contact microphones,
audio transmitters located in AC
outlets, and laser/microwave
reflections from windows.

Most sound masking systems inject
noise into an otherwise benign
environment. In this environment,
the occupants must raise their
voices above the noise level to
communicate, which invariably,
eliminates the benefit of noise
masking. The masking system injects
noise into the environment perimeter
and not directly into the
environment. This approach allows
normal conversation while defeating
eavesdropping devices that rely on
acoustic leakage.

FeaturesThe ANG-2200 offers two channels
each with a truly random noise
source. Both channels have a
separate high and low frequency
control in order to compensate for
loses found in the environments
material composition.
